Which term is used to describe a part of the body that is positioned further away from the midline?

The term that describes a part of the body that is positioned further away from the midline is "lateral." When referring to anatomy, the midline refers to an imaginary line that divides the body into equal right and left halves. Structures situated toward the side of the body, away from this midline, are termed lateral.

For example, in anatomical terms, the arms are lateral to the torso because they are positioned further away from the midline of the body. Understanding this terminology is essential for accurately describing the location of various body parts in relation to one another, which is foundational in fields such as fitness training, anatomy, and healthcare.

The other terms serve different purposes in anatomy: "medial" refers to being closer to the midline, "proximal" indicates a position nearer to the point of attachment or a specified reference point, and "distal" means further away from that reference point. Hence, "lateral" is the appropriate term for indicating a position away from the midline.
